[Class 38 (ii)] Relates to a variable leakage transformer having a movable winding particularly for use in resistance and are welding and consists in the provision of a core having a curved part 7, Fig. 1, the ends of which are joined by one or more straight parts 4, 8, 9, the moving coil 5 being mounted on the curved part. In the form shown the curved part 7 is semicircular and the moving coil 5 is pivoted to move about the centre 6. The cross-section of the core part 7 may be varied along its length, either continuously or discontinuously, in order to obtain particular regulation effects. In a modification, the moving primary coil 5 may be connected in series with an additional fixed coil mounted on the core part 8. The transformer may also be provided with two or more secondaries. To give additional voltage regulation the windings may be tapped. If desired the moving coil may be flexibly connected to the operating mechanism so that a certain amount of deflection depending on load current can take place. As shown in Fig. 4, the moving coil 24 is mounted on a lever 28 which is connected by a spring 32 to the adjusting spindle 27 by a plate 31. The spring is anchored to a pin in a slot 33 so that adjustment of tension can be effected. A 3-phase to 2-phase arrangement can be formed by means of two of these transformers.

[Also in Divisions B1, F1 and F2] A relief valve has a pressure port 3 for connection to the interconnected inflatable telescopic struts of a pneumatic vehicle suspension system, an exhaust port 8 in a spring-loaded piston 4 and a manually movable closure member 11. In normal operation the piston 4 will move away from the closure member 11 to relieve the system and if the pressure of the system is to be altered the dashboard actuating lever 18 is moved. Leftward movement of the lever 18 opens the exhaust port and the piston 4 follows the movement of the closure member until the valve is closed at the new reduced pressure selected. Rightward movement of the lever closes a micro switch 19 held open by abutment with valve plunger 9 to actuate a compressor which raises the pressure in the system until the valve plunger piston 4 combination has moved sufficiently to the right to open the micro switch 19. The valve plunger may be directly moved manually when it has spaced grooves there about to indicate the position of the valve. The piston 4 may be replaced by a piston cup sealed by a rolling diaphragm. A non-return valve for connection in the compressor outlet has an elastomeric 0-ring 44 seated in a V- shaped groove and controlling the flow through a radial bore between the groove and the inlet 43.

Title: Method of making selenium rectifiers
IPC: H01L21/108
Filed: 1953-05-15
Abstract: 721,109. Semi-conductor devices. STANDARD TELEPHONES & CABLES, Ltd. May 15, 1953 [June 27, 1952], No. 13661/53. Class 37. In a method of producing selenium or other rectifiers, an artificial barrier layer in the form of fine particles is precipitated on the semiconductor layer by electrostatic attraction. Insoluble substances like quartz may thus be used. In one embodiment, negatively-charged particles are passed over the positively-charged semi-conductor layer, which at this stage is in the insulating state, in a stream of gas. In another system an insulating belt carries a fine charged powder beneath the charged semiconductive layer, whereby only particles below a critical size reach the plate against gravity. Both processes are carried out in darkness but the rectifier plates may previously be exposed to light through a template, of grating form for example, so partially removing the charge in places by photoconductivity and resulting in a patterned barrier layer. A suitable template produces a layer thicker at the edges where break-through normally occurs. In the following heat treatment where pressure is required on the selenium layer it is essential that the barrier layer adheres more strongly to the selenium than to the pressure stamp.

Abstract: 438,575. Change-speed epicyclic gearing. AHLGREN, T. H., 32, Kungsgatan, Gothenburg, Sweden. May 13, 1935, No. 13956. Convention date, Dec. 14, 1934. [Class 80 (ii)] Relates to two-speed three-element spur epicyclic gearing suitable for cycles of the kind in which either the annulus 6 is fixed while the sun 7 is rotary, as shown in Fig. 1, or the sun 7 is fixed and the annulus 6 is rotary, as shown in Fig. 2. In each case, a carrier 3 of planet gears 5 is rigid with a driving central axle 1 which turns within a fixed bracket 13 and to which the cycle pedals 15 are secured. In the form shown in Fig. 1, the sun 7 is rigid with a sleeve 8 which is splined on a driven sleeve 2 and which carries a flange 10 with clutch recesses 9. In the position shown, in which the sleeve 10 is held at right by a spring 23, a high ratio of overdrive is imparted to the sleeve 2. A transmitting sprocket 21 upon the sleeve 2 need not therefore be made large, as is usual. To change speed to direct drive, the sleeve 8 is thrust left against the spring 23 by a control lever 18 until the recesses 9 engage over projecting ends 4 of the spindles of the planet gears 5. The drive then passes from the carrier 3 through the flanged sleeve 8 to the driven sleeve 2, the toothed gearing being idle. In the form shown in Fig. 2, the annulus 6 is rigid with the sleeve 8 splined on the driven sleeve 2. In the position shown, the planets roll on the fixed sun 7 and the annulus 6 and sleeves 8, 2 are driven at a speed which is increased, but not so much so as in the other form. To change speed to the direct drive, the sleeve 8 is slid left until clutch recesses 9 in the flange 10 engage over the projecting ends 4 of the planet spindles effecting a 1 to 1 drive, as before.

Filed: 1941-11-03
Abstract: 554,197. Pneumatic shock-absorbers. KIGASS, Ltd., and GRET, C. A. Nov. 3,1941, Nos. 14123/41, 15552/41, 4322/42, and 14109/42. [Class 108 (iii)] A shock-absorbing device for aircraft is provided with a gas chamber 1, a piston 2 slidable therein, and means effective when the aircraft lands for lowering the gas pressure in said chamber to provide a longer stroke of the piston relative to the chamber during subsequent taxying of the aircraft. In the construction shown in Fig. 1, the annular piston 2 compresses air or gas into the primary chamber 1, there being, however, some leakage through the Alving grooves 8 of varying lengths in the fixed stem 7 which is held concentric with the cylinder by the partition 4 between the primary chamber 1 and the secondary chamber 3. The shock of landing creates a temporary excessive pressure which moves piston 13 in the end of stem 7 whereby sleeve valve 6 is opened momentarily so that some of the compressed air in chamber 1 passes into chamber 3 from which it can only return slowly past ball valve 18. The lower pressure in main chamber 1 facilitates taxying for a limited period. In one modification the sleeve valve 6 is replaced by a lift valve. In another modification the stem 7 and the partition 4 are movable against the resistance of the air in the secondary chamber 3 and against a spring. In another form a spring-controlled lift or disc valve is arranged in partition 4.
